Two-dimensional motion is the study of movement in two directions, including the study of motion along a curved path, such as projectile and circular motion. In this lesson, you will have the opportunity to explore some of the foundational concepts of projectile and circular motion by analyzing a variety of representations including descriptions, illustrations, graphs, charts, and equations.
